This is the opposite of the common carrier model. In the common carrier model, there are many companies that you can choose from as a consumer from the get go, because the network is unbundled from a single company.
Secondly, part of the common carrier model is that if the government is not convinced that the common carrier is acting in the public's best interest - for example, if they are delaying needed upgrades - then the government can simply confiscate the common carrier's assets, and sell them to a company that will actually meet its QoS and upgrade obligations, or spin the whole thing off as a SoE.
